AT VANGUARD, WE BELIEVE THAT TRADITION MATTERS

Our 8,000 crew members embrace the traditional values on which our success is
built, including integrity, hard work, thrift, teamwork, and fair dealing on
behalf of our clients. 

This year, our report cover pays homage to three anniversaries, each of great
significance to The Vanguard Group:
  
- - The 200th anniversary of the Battle of the Nile, which commenced on August 1,
  1798. HMS Vanguard, the victorious British flagship at the Nile, is our
  namesake. And its motto--"Leading the way"--serves as a guiding principle for
  our company.

- - The 100th birthday, on July 23, of Walter L. Morgan, founder of Wellington
  Fund, the oldest member of what became The Vanguard Group. Mr. Morgan was
  friend and mentor to Vanguard founder John C. Bogle, and helped to shape the
  standards and business principles that Mr. Bogle laid down for Vanguard at its
  beginning nearly 25 years ago: a stress on balanced, diversified investments;
  insistence on fair dealing and candor with clients; and a focus on long-term
  investing. To our great regret, Mr. Morgan died on September 2.

- - The 70th anniversary, on December 28, of the incorporation of Vanguard
  Wellington Fund. It was the nation's first balanced mutual fund, and is one of
  only a handful of funds created in the 1920s that are still in operation.

Although Vanguard constantly tackles new challenges, adopts new technology, and
develops new services, we treasure the traditions and values that set us apart
in a crowded, competitive industry. And we salute our shareholders, whose
support and trust we strive to earn each and every day.

Interest rates declined on balance during the twelve months ended November 30,
1998--the fiscal year for the Vanguard California Tax-Exempt Funds--providing a
significant boost to prices of tax-exempt municipal bonds. In this bond-friendly
environment of lower rates and tame inflation, the +3.1% return of our
California Tax-Exempt Money Market Fund, the +7.5% return of our California
Insured Intermediate-Term Tax-Exempt Fund, and the +8.3% return of our
California Insured Long-Term Tax-Exempt Fund exceeded the results of their
peers.

       The table at right presents each fund's twelve-month return along with
its income and capital components. The total return (capital change plus
reinvested dividends) of the Insured Long-Term Tax-Exempt Fund return is based
on a change in net asset value from $11.45 per share on November 30, 1997, to
$11.73 per share on November 30, 1998, adjusted for dividends totaling $0.577
per share paid from net investment income and a distribution of $0.069 per share
paid from net realized capital gains. The Insured Intermediate-Term Fund's
return is based on a change in net asset value from $10.66 per share on November
30, 1997, to $10.95 per share on November 30, 1998, adjusted for dividends
totaling $0.489 per share paid from net investment income. The Money Market
Fund's net asset value remained at $1 per share, as was expected but not
guaranteed. At the end of the fiscal year, the Insured Long-Term Fund's yield
stood at 4.33%, the Insured Intermediate-Term Fund's yield at 3.87%, and the
Money Market Fund's yield at 2.74%.

FINANCIAL MARKETS IN REVIEW

During the twelve months ended November 30, investors fretted over a variety of
developments both here and abroad, from the debt problems of foreign governments
to a huge hedge-fund bailout to growing concern about corporate profits.
Overall, the uncertainty made for a tumultuous, but ultimately rewarding, period
in the equity markets and a fine fiscal year for bonds.

       The yield of the benchmark 30-year U.S. Treasury bond fell about 100
basis points on balance, ending the period at 5.06% after bottoming out at 4.72%
in early October. During the autumn, the Federal Reserve Board trimmed
short-term rates three times in seven weeks by a total of 0.75 percentage point,
citing the strain of international woes on the U.S. economy. The economy
continued to exhibit steady growth (about 3% during the period), and inflation
remained low. Consumer prices were up just 1.5% for the fiscal year.

       Of course, as interest rates drop, bond prices rise. That meant
outstanding returns for bonds during the fiscal year, particularly for
longer-maturity issues, which benefit most from interest-rate declines. The
Lehman Brothers Long U.S. Treasury Bond Index earned a total return of +15.7%,
with its +7.2% income return augmented by an +8.5% capital return.


                                       1
<PAGE>   4

       Yields on high-grade long-term municipal bonds did not fall as far as
those for Treasury securities. Top-rated long-term municipal bonds ended the
fiscal year with a yield of 4.89%, down from 5.25% at the end of November 1997.
Yields on top-grade (MIG-1) 3-month notes, which are more sensitive than
longer-term issues to changes in short-term interest rates, declined on balance
to 2.95% from 3.80% a year earlier. For the twelve months, the Lehman 10 Year
Municipal Bond Index, a good measure of the long-term municipal market, returned
+8.1%--an outstanding return considering the tax advantages of municipal bonds
and the extremely low inflation rate.

       The U.S. stock market, meanwhile, weathered a severe summer storm that
drove the broad market down nearly -20% and clipped more than 40% from the value
of many smaller stocks. A swift recovery ensued during the final three months of
the fiscal year, and for the twelve months, the Standard & Poor's 500 Composite
Stock Price Index was up +23.7%.

       The 1998 fiscal year will likely be remembered as a period of
extraordinary relative value in the municipal bond market. On November 30,
yields on long-term U.S. Treasuries and long-term municipal bonds were nearly
identical--a truly remarkable occurrence, given that income from state-specific
municipal bond funds is exempt from federal, state, and local taxes for state
residents. The yield convergence has been the result of several factors.
Treasury bonds benefited from both an easing of inflation fears and a "flight to
quality" by foreign investors--particularly from Asia--who bought Treasury
securities to protect themselves from declines in their currencies versus the
U.S. dollar. Meanwhile, new Treasury issuance dropped--thanks to the federal
budget surplus--and issuance of new municipal bonds soared, dampening prices a
bit and keeping yields high in relation to Treasuries.

       Throughout the summer and into the fall, yields of long-term municipal
bonds were equal to about 98% of the yield on comparable Treasuries, and on
several occasions muni yields matched or even slightly exceeded Treasury yields.
To be sure, this phenomenon is temporary, but it made municipal bonds as
valuable in relation to Treasuries as they've ever been. Historically, municipal
bonds have offered a yield equal to about 84% of the yield on Treasury bonds.

       It's always important to view the performance of bonds in the proper
perspective, especially after a year when declining interest rates pushed
returns higher. As you may recall, during the past two fiscal years bond prices
received only a small capital boost. Just four years ago, in 1994, interest
rates rose sharply and bond prices plunged, providing a painful lesson about the
volatility of bond-fund returns. It is also important for investors to
understand that the ever-present fluctuations in the bond market tend to offset
each other over longer periods, leaving the rate of interest income as the
dominant long-term source of bond returns.

FISCAL 1998 PERFORMANCE OVERVIEW

The +8.3% return of the Vanguard California Insured Long-Term Tax-Exempt Fund
topped the +7.3% return of the average California municipal bond fund and the
+7.8% return of the unmanaged Lehman Municipal Bond Index. This index, which
includes municipal bonds from across the country, is a notoriously tough
competitor because it does not incur the "real world" operating expenses and
transaction costs that all mutual funds must bear. Though the majority of our
total return came from interest income, the fund earned a capital return of
+3.1% that reflected the interest-rate decline.


                                       2
<PAGE>   5

       Our Intermediate-Term Tax-Exempt Fund earned a +7.5% return that outpaced
the +6.7% return of the average intermediate-term California municipal bond fund
and the +7.3% return of the unmanaged Lehman 7 Year Municipal Bond Index. Our
Tax-Exempt Money Market Fund provided a total return of +3.1%, outpacing the
+2.8% return of its average peer.

THE MUNICIPAL BOND TAX ADVANTAGE

For California residents, the income earned by our funds is exempt from state,
local, and federal income taxes. At current yields, that means that investors in
long-term tax-exempt municipal bonds who are taxed at the highest marginal tax
rate can earn an astounding 65% more after-tax income than they could in a
comparable long-term U.S. Treasury bond fund, and investors in insured
intermediate-term municipal bonds can earn 50% more after-tax income than in
comparable Treasury securities. Our Tax-Exempt Money Market Fund also offers
California residents a distinct advantage over Treasuries with similar
maturities. On November 30, the yield of MIG-1 notes was 11% higher than the
after-tax yield of 90-day U.S. Treasury bills. To look at this another way, a
yield of 5.1% on a tax-exempt long-term bond would be the equivalent of an 8.4%
taxable yield for California taxpayers subject to the highest tax rates. For a
tax-exempt short-term yield of 3.0%, the taxable equivalent would be 5.0%.

       These remarkable advantages are illustrated in the table at right, which
compares the annual net income earned on tax-exempt and taxable U.S. Treasury
securities as of November 30, 1998, assuming a $100,000 investment. Our
illustration assumes current yields (as of November 30, 1998) of 5.1% for
long-term U.S. Treasury bonds, 4.7% for intermediate-term U.S. Treasury bonds,
4.5% for U.S. Treasury bills, 5.1% for long-term municipals, 4.2% for
intermediate-term municipals, and 3.0% for short-term municipals.

The tax adjustment assumes a typical itemized tax return based on a federal tax
rate of 39.6%; local taxes are not considered. The illustration is not intended
to represent future results. 

       Of course, in terms of credit quality, state-specific municipal bond
funds, by definition, don't match up to U.S. Treasury bond funds, whose
securities are backed by the full faith and credit of the U.S. government. Also,
single-state municipal bond funds lack geographic diversification. Private
insurance on the bonds in our Long-Term Tax-Exempt and Intermediate-Term
Tax-Exempt Funds, however, substantially mitigates these additional credit
risks. Though the insurance does not provide protection against fluctuations in
the funds' value, it guarantees full payment of interest and principal for our
bond holdings.

       Portfolio insurance generally is not available for short-term securities,
so our investment adviser, Vanguard Fixed Income Group, is responsible for
preserving the principal of the Tax-Exempt Money Market Fund--a responsibility
the group fulfilled admirably. We remind you that money market investments are
not guaranteed by the Federal Deposit Insurance Corporation, which insures bank
accounts and certificates of deposit.

LONG-TERM PERFORMANCE OVERVIEW

The table below compares the longer-term performance of our funds with those of
their average peer mutual funds. It also illustrates our performance edge over
our competitors, based on hypothetical investments of $10,000 made a decade ago
in our funds (since inception for the Insured Intermediate-Term Fund) and their
average competitors.

       Our edge is explained, in part, by our lower expenses, a powerful--and,
we believe, sustainable--advantage that helps us toward our goal of providing
returns that exceed those of competitive norms. Our funds maintain expense
ratios (annual expenses as a percentage of average net assets) of about 0.20%,
far below the 1.03% charged by the average long-term state tax-exempt fund, the
0.92% charged by the average intermediate-term state tax-exempt fund, and the
0.53% charged by the average state tax-exempt money market fund. Our success is
also the result of the skillful management of Vanguard Fixed Income Group, which
has helped guide our funds to their superior record while maintaining the
highest investment quality in the industry.

**Annualized returns since inception on March 4, 1994.

       We emphasize that the longer-term returns shown above are higher than
investors should expect with interest rates at current levels. The returns of
our Insured Long-Term and Insured Intermediate-Term Funds have been boosted by
capital appreciation due to generally declining interest rates since 1990. But
interest rates cannot decline forever. The best indicator of the average future
return on long-term bonds--and it is not a perfect predictor--is the current
yield on those bonds.

IN SUMMARY

The excellent returns earned by bonds over the past twelve months--as well as
over the past decade--should not lull investors into a false sense of security
about the safety of bonds or the reliability of returns. Bond returns will
inevitably revert to their historical (lower) averages, possibly with little or
no warning.

       We believe that the specific risks of bonds, and the general risks of
investing, can be managed by a balanced investment program that includes stock
funds, bond funds, and money market funds suited to an individual's objectives,
time horizon, tolerance for risk, and financial situation. Once you have such a
program, you should be prepared to stick with it through good times and bad.

NOTE: You'll observe that we have made minor changes in the names of the
Vanguard California Tax-Exempt Funds. We replaced the word "Tax-Free" with
"Tax-Exempt" and replaced "Portfolio" with "Fund" as part of a broader effort to
clarify the names in our fund lineup.


NOTICE TO SHAREHOLDERS

At a special meeting on July 24, 1998, shareholders of the Vanguard California
Tax-Exempt Funds overwhelmingly approved six proposals. The proposals and voting
results were:

1. REORGANIZATION INTO A DELAWARE BUSINESS TRUST. Based on the funds' assets at
the time of the vote, this change will reduce the amount of state taxes paid
each year by some Vanguard funds. The Vanguard California Tax-Exempt Funds will
not realize any tax savings as a result of the change, but the funds will
benefit from the efficiency of being organized the same way as all other
Vanguard funds. Approved by 95.73% of the shares voted, as follows:

2a. INVESTMENT LIMITATION CHANGES--INTERFUND LENDING PROGRAM. This change
permits the California Tax-Exempt Funds to participate in Vanguard's interfund
lending program, which allows funds to loan money to each other if--and only
if--it makes good financial sense to do so on both sides of the transaction. The
interfund lending program won't be an integral part of the funds' investment
programs; it is a contingency arrangement for managing unusual cash flows.

THE MARKETS IN PERSPECTIVE
YEAR ENDED NOVEMBER 30, 1998

[PHOTO]

U.S. financial markets produced solid overall gains during the fiscal year ended
November 30. The S&P 500 Index gained 23.7% for the 12-month period, overcoming
a sharp summer setback. Bond prices rose as interest rates declined. Returns
from overseas stock markets varied widely, with big gains in Europe and losses
in most other markets.

U.S. STOCK MARKETS

The stock market's gains during the fiscal year were concentrated in
large-capitalization growth stocks. Within the S&P 500 Index, the growth stocks
rose 33.7%, while the value stocks were up 13.2%. The market's overall bias
toward large-caps showed starkly in the contrast between the S&P 500 and other
indexes. While the S&P 500 was rising 23.7%, the rest of the market returned a
paltry 2.6%, as measured by the Wilshire 4500 Equity Index. Small-cap stocks, as
represented by the Russell 2000 Index, did even worse--a negative return of
6.6%.

       The market's ascent was not without incident, even for large-cap stocks.
After rising strongly to a record high on July 17, the S&P 500 fell by 19.2%
during the following six weeks, just shy of the 20% mark generally considered
the boundary distinguishing a bear market from a mere "correction." Declines
were certifiably bearish for smaller stocks, however.

       The July-August tumble in stock prices reflected a number of factors that
collectively raised the anxiety level for many investors. Among these were
deteriorating corporate earnings reports and forecasts, Russia's default on its
debts, and a continuance of economic weakness in Asia. The persistence of Asia's
economic troubles--which first surfaced in mid-1997--began to slow the economic
expansions in the United States and Europe.

</TABLE>

       The rebound in stocks late in the fiscal year occurred even though
several sources of uncertainty remained, including doubts about global economic
growth and reductions in securities analysts' forecasts of future corporate
earnings. Stock prices got considerable help from the decline in interest rates.
(Low inflation and low interest rates help stock prices by raising the estimated
value of future dividends and earnings.)

       Three forces clearly shaped the performance of industry sectors. They
could be summarized as faith (the buoyant confidence of consumers), fear
(related to the effects of economic troubles abroad), and fortresses (companies
somewhat protected from competition).


                                       7
<PAGE>   10

       In contrast to the cautious stance of investors during fiscal 1998, U.S.
consumers threw caution to the wind. Feeling flush because of plentiful jobs
(the nation's unemployment rate was 4.4% at fiscal year-end) and rising wages,
consumers spent a record proportion of their income. Not surprisingly, then, two
big gainers among sectors of the S&P 500 Index were consumer discretionary
firms, such as retailers (+26%) and consumer staples (+22%).

       Fear was a factor in the lagging returns in industry groups considered to
be vulnerable to slowing global growth, falling commodity prices, and tougher
price competition from foreign suppliers. Among these--all traditional value
sectors--were firms in the "other energy" category (-37%); chemical and other
materials & processing firms (essentially a zero return); and makers of producer
durables such as airplanes and machinery (+2%). Conversely, utilities did well
(+35%) in part because they are seen as relatively insulated from foreign
competition or economic woes. Fortresses are companies perceived as relatively
safe from competitors because of patented products or brands. Such companies led
the year's best-performing sectors: technology (+49%) and health care (+43%).

U.S. BOND MARKETS

Interest rates declined during the fiscal year, especially for U.S. Treasury
securities, which benefited from heightened aversion to risk among investors and
from a slight decrease in supply, thanks to a $70 billion federal budget
surplus. The Federal Reserve Board had the flexibility to cut short-term rates
in three quarter-point steps in the autumn because inflation was remarkably
tame--consumer prices rose just 1.5% for our fiscal year.

       In this bond-friendly environment, yields on long-term Treasury issues
fell by roughly 100 basis points (1 percentage point), with the 30-year Treasury
bond ending the fiscal year at 5.06%. Lower rates mean higher prices for bonds,
and the Lehman Brothers Long U.S. Treasury Bond Index earned a total return of
15.7%, an astounding margin of some 14 percentage points over the inflation
rate.

       Reflecting investors' flight to quality and worries about slowing
economic growth, prices fell for high-yield "junk" bonds. Even high-quality
corporate bonds and mortgage-backed securities did not rise in price as far as
Treasury securities. Mortgage bonds tend to lag Treasuries during periods when
falling rates lead to greater refinancing activity by homeowners, resulting in
unwanted prepayments of principal. The Lehman Aggregate Bond Index, which
comprises high-quality corporate and mortgage-backed bonds as well as
Treasuries, and has an intermediate-term average maturity, earned 9.5%.

       Yields on long-term municipal bonds declined only modestly during the
fiscal year, and by November 30 were only slightly lower than yields on
comparable Treasury securities. This was striking because the interest on
municipals is exempt from federal income tax.

INTERNATIONAL STOCK MARKETS

Europe's stock markets outdistanced even the S&P 500 Index, but Asian and Latin
American markets were generally down during the fiscal year. As a group,
European stocks earned 27.8% in U.S.-dollar terms. Europe's bull market was
fueled by continuing economic growth, lower interest rates, increased corporate
merger activity, and optimism about the effects of the euro, a common currency
due to be adopted in 1999 by 11 nations.

       Japan's stock market continued to suffer from the effects of a severe
recession and a shaky banking system. Stocks in Tokyo fell 4.5% in U.S.-dollar
terms. Elsewhere in Asia, returns were mixed, ranging from a rebound of 21% in
South Korea, through Australia's 11% gain, to big losses in Indonesia (-52%),
Malaysia (-42%), New Zealand (-25%), and Singapore (-18%). Losses were steep
throughout Latin America, including Mexico (-32%), Venezuela (-59%), Brazil
(-20%), and Chile (-22%).

REPORT FROM THE ADVISER

[PHOTO]

During the fiscal year ended November 30, nervous global investors flocked to
the safety of U.S. Treasury securities. The "flight to quality" began with the
collapse of Asian markets early in the year, then spread throughout the emerging
economies of the world. With each round of negative world events, U.S. Treasury
yields fell as investors bid up bond prices. In contrast to the volatility on
world financial markets, sailing was smooth for the U.S. economy, which produced
stable growth and low inflation. The Federal Reserve Board initially was
reluctant to lower short-term interest rates in the face of the fundamental
strength of the domestic economy; however, signs of international economic
calamity loomed ever larger, threatening future U.S. growth. By the second half
of our fiscal year, it was clear that domestic export-sensitive sectors were
slowing, and stock market volatility increased. The Fed then cut short-term
interest rates by a total of three-quarters of a percentage point. To date, the
Fed's action has helped calm the fears of a worldwide credit crunch and stemmed
investors' flight from risk. We will have to wait and see whether the worst is
over for global markets.

       As one would expect, municipal bond yields fell in sympathy with the
decline in Treasury yields. However, a large supply of new tax-exempt bonds
muted the price increases. Consequently, municipal bonds underperformed their
Treasury bond counterparts. During the fiscal year, the benchmark 30-year U.S.
Treasury bond yield declined nearly 1 percentage point (from 6.05% to 5.06%). In
contrast, the yield on an AAA-rated tax-exempt bond of similar maturity declined
only three-tenths of 1 percent (from roughly 5.2% to 4.9%), and produced
commensurately less price appreciation.

       As noted, the supply of new tax-exempt bonds grew dramatically during our
fiscal year. Two factors led to this increase in municipal debt. First, as
interest rates declined, municipalities rushed to issue new bonds that would
refinance their older, higher-coupon debt. Second, the financial strength of
many states and localities improved as robust economic performance boosted tax
revenues. This increased financial sustenance allowed many issuers to fund new
capital projects with tax-exempt debt. In all, tax-exempt issuance for the year
was up 27% to $278 billion in new bonds.

       This abundance of new bonds offers unique value to investors in
longer-term municipal issues. As of our fiscal year-end, the yield on a
high-quality, long-maturity municipal bond was equal to an unusually high 96.8%
of the yield on a comparable U.S. Treasury security. At certain points during
the fiscal period, AAA-rated insured municipal bonds actually offered yields
higher than Treasury bonds, a situation not seen since 1986. For investors in
the maximum federal tax bracket (39.6%), high-grade municipal bonds offer about
3 percentage points in additional taxable-equivalent yield over comparable U.S.
Treasuries. Our state tax-exempt funds further boost after-tax returns by
providing income exempt from state tax. In the past, municipal bond yields have
not stayed 


                                       9
<PAGE>   12

high relative to Treasury bonds for long. However, because of the
persistence of global uncertainty and its beneficial effect on prices of
Treasury bonds, at present it's hard to predict when municipal yields will
return to more-normal levels. In the meantime, longer-term municipal bonds are a
steal.

       The high credit quality of the Vanguard California Tax-Exempt Funds
played an important role in our strong performance relative to peers. Early in
our fiscal year, demand was quite strong for the higher yields of uninsured
bonds and those of speculative-grade credit quality. Market participants
disregarded the added credit risk they were assuming. Demand for lower-quality
securities was so high that investors accepted ever-smaller yield premiums for
assuming the extra credit risk, and yield spreads between bonds of different
quality tightened. But the bankruptcy of a major hospital group in Pennsylvania
in summer 1998 caused many bondholders to reconsider the relationship between
yield and credit quality.

       Investors in Vanguard's insured single-state tax-exempt funds receive
additional credit protection. Although this municipal bond insurance does not
protect against changes in market value, it does guarantee the timely payment of
principal and interest. Our single-state tax-exempt funds are able to offer the
dual benefits of high credit quality and attractive yields year after year
because of our low expenses. Our emphasis on high credit quality should allow
our shareholders to sleep comfortably.

       Over time, the simple combination of a disciplined risk approach with low
expenses has proven to be a powerful force for maximizing total return for
shareholders. Our continued focus on these basics produced the desired results
in fiscal 1998.

       Yields on 1-year tax-exempt money market instruments fell 76 basis points
(0.76 percentage point) during the second half of our fiscal year, even though
summer is traditionally a season for heavy municipal borrowing. Over the full 12
months, the decline was 82 basis points, leaving the yield on the benchmark
1-year MIG-1 note at 2.99% on November 30. By comparison, the yield on 1-year
U.S. Treasury bills fell 92 basis points during the second half and 99 basis
points for the full year, closing with a yield of 4.50%. The plunge in
short-term yields was fueled by the global "flight to quality" and by the Fed's
75-basis-point cut in the fed funds rate. At fiscal year-end, the yield on
1-year MIG-1 notes therefore was equal to 66.4% of the yield on comparable
Treasury bills. Though this ratio is less favorable than that for yields of
long-term municipal bonds in relation to those of Treasury bonds, municipal
money markets still offer value for investors in the highest tax brackets.

       As the new year begins, the California Tax-Exempt Money Market Fund is
positioned to take advantage of its dual strengths of conservative,
quality-oriented management and low expenses. We believe these attributes will,
over time, generate superior risk-adjusted returns.

INVESTMENT PHILOSOPHY

The adviser believes that each fund, while operating within stated maturity and
stringent quality targets, can achieve a high level of current income that is
exempt from federal and California income taxes by investing in insured and
high-quality uninsured securities issued by California state, county, and
municipal governments.

PERFORMANCE SUMMARY
CALIFORNIA TAX-EXEMPT MONEY MARKET FUND

All of the data on this page represent past performance, which cannot be used to
predict future returns that may be achieved by the fund. Note, too, that returns
can fluctuate widely. An investment in a money market fund is neither insured
nor guaranteed by the U.S. government, and there is no assurance that the fund
will be able to maintain a stable net asset value of $1 per share.

AVERAGE COUPON. The average interest rate paid on the securities held by a fund.
It is expressed as a percentage of face value.

AVERAGE DURATION. An estimate of how much a bond fund's share price will
fluctuate in response to a change in interest rates. To see how the price could
shift, multiply the fund's duration by the change in rates. If interest rates
rise by one percentage point, the share price of a fund with an average duration
of five years would decline by about 5%. If rates decrease by a percentage
point, the fund's share price would rise by 5%.

AVERAGE MATURITY. The average length of time until bonds held by a fund reach
maturity (or are called) and are repaid. In general, the longer the average
maturity, the more a fund's share price will fluctuate in response to changes in
market interest rates.

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
ratings assigned to a fund's securities holdings by credit-rating agencies. The
agencies make their judgment after appraising an issuer's ability to meet its
obligations. Quality is graded on a scale, with Aaa or AAA indicating the most
creditworthy bond issuers and A-1 or MIG-1 indicating the most creditworthy
issuers of money market securities.

BETA. A measure of the magnitude of a fund's past share-price fluctuations in
relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20 would have seen its share price rise or fall by 12% when the overall
market rose or fell by 10%.

CASH RESERVES. The percentage of a fund's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate bond
investment.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a fund's securities by credit
rating can help in gauging the risk that returns could be affected by defaults
or other credit problems.

DISTRIBUTION BY MATURITY. An indicator of interest-rate risk. In general, the
higher the concentration of longer-maturity issues, the more a fund's share
price will fluctuate in response to changes in interest rates.

EXPENSE RATIO. The percentage of a fund's average net assets used to pay its
annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

INVESTMENT FOCUS. This grid indicates the focus of a fund in terms of two
attributes: average maturity (short, medium, or long) and average credit quality
(high, medium, or low).

NUMBER OF ISSUES. An indicator of diversification. The more separate issues a
fund holds, the less susceptible it is to a price decline stemming from the
problems of a particular issue.

R-SQUARED. A measure of how much of a fund's past returns can be explained by
the returns from the overall market (or its benchmark index). If a fund's total
return were precisely synchronized with the overall market's return, its
R-squared would be 1.00. If a fund's returns bore no relationship to the
market's returns, its R-squared would be 0.

YIELD. A snapshot of a fund's interest income. The yield, expressed as a
percentage of the fund's net asset value, is based on income earned over the
past 30 days (7 days for money market funds) and is annualized, or projected
forward for the coming year.

YIELD TO MATURITY. The rate of return an investor would receive if the
securities held by a fund were held to their maturity dates.

FINANCIAL STATEMENTS
NOVEMBER 30, 1998

[PHOTO]

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each fund's municipal bond holdings,
including each security's market value on the last day of the reporting period
and information on credit enhancements (insurance or letters of credit).
Securities are grouped and subtotaled according to their insured or noninsured
status. Other assets are added to, and liabilities are subtracted from, the
value of Total Municipal Bonds to calculate the fund's Net Assets. Finally, Net
Assets are divided by the outstanding shares of the fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

      At the end of the Statement of Net Assets, you will find a table
displaying the composition of the fund's net assets on both a dollar and
per-share basis. Undistributed Net Investment Income is usually zero because the
fund distributes its net income to shareholders as a dividend each day. Any
realized gains must be distributed annually, so the bulk of net assets consists
of Paid in Capital (money invested by shareholders). The balance shown for
Accumulated Net Realized Gains usually approximates the amount available to
distribute to shareholders as taxable capital gains as of the statement date,
but may differ because certain investments or transactions may be treated
differently for financial statement and tax purposes. Any Accumulated Net
Realized Losses, and any cumulative excess of distributions over net realized
gains, will appear as negative balances. Unrealized Appreciation (Depreciation)
is the difference between the value of the fund's investments and their cost,
and reflects the gains (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.

STATEMENT OF OPERATIONS

This Statement shows interest earned by each fund during the reporting period,
and details the operating expenses charged to the fund. These expenses directly
reduce the amount of investment income available to pay to shareholders as
tax-exempt income dividends. This Statement also shows any Net Gain (Loss)
realized on the sale of investments, and the increase or decrease in the
Unrealized Appreciation (Depreciation) on investments during the period. If a
fund invested in futures contracts during the period, the results of these
investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. Because the fund distributes its income
to shareholders each day, the amounts of Distributions--Net Investment Income
generally equal the net income earned as shown under the Operations section. The
amounts of Distributions--Realized Capital Gain may not match the capital gains
shown in the Operations section, because distributions are determined on a tax
basis and may be made in a period different from the one in which the gains were
realized on the financial statements. The Capital Share Transactions section
shows the amount shareholders invested in the fund, either by purchasing shares
or by reinvesting distributions, and the amounts redeemed. The corresponding
numbers of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis. It also presents the fund's Total Return and
shows net investment income and expenses as percentages of average net assets.
These data will help you assess: the variability of the fund's net income and
total returns from year to year; the relative contributions of net income and
capital gains to the fund's total return; how much it costs to operate the fund;
and the extent to which the fund tends to distribute capital gains.

      The table also shows the Portfolio Turnover Rate, a measure of trading
activity. A turnover rate of 100% means that the average security is held in the
fund for one year. Money market funds are not required to report a Portfolio
Turnover Rate.

NOTES TO FINANCIAL STATEMENTS

Vanguard California Tax-Exempt Funds comprises the California Tax-Exempt Money
Market Fund, California Insured Intermediate-Term Tax-Exempt Fund, and
California Insured Long-Term Tax-Exempt Fund, each of which is registered under
the Investment Company Act of 1940 as an open-end investment company, or mutual
fund. Each fund invests in debt instruments of municipal issuers whose ability
to meet their obligations may be affected by economic and political developments
in the state of California.

A.   The following significant accounting policies conform to generally accepted
accounting principles for mutual funds. The funds consistently follow such
policies in preparing their financial statements.

     1. SECURITY VALUATION: Tax-Exempt Money Market Fund: Investment securities
are valued at amortized cost, which approximates market value. Other funds:
Bonds, and temporary cash investments acquired over 60 days to maturity, are
valued using the latest bid prices or using valuations based on a matrix system
(which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not available are valued by methods
deemed by the Board of Trustees to represent fair value.

     2. FEDERAL INCOME TAXES: Each fund intends to continue to qualify as a
regulated investment company and distribute all of its income. Accordingly, no
provision for federal income taxes is required in the financial statements.

     3. FUTURES CONTRACTS: Each fund, except the Tax-Exempt Money Market Fund,
may use Municipal Bond Index, U.S. Treasury Bond, and U.S. Treasury Note futures
contracts, with the objectives of enhancing returns, managing interest-rate
risk, maintaining liquidity, diversifying credit risk and minimizing transaction
costs. The funds may purchase or sell futures contracts instead of bonds to take
advantage of pricing differentials between the futures contracts and the
underlying bonds. The funds may also seek to take advantage of price differences
among bond market sectors by simultaneously buying futures (or bonds) of one
market sector and selling futures (or bonds) of another sector. Futures
contracts may also be used to simulate a fully invested position in the
underlying bonds while maintaining a cash balance for liquidity. The primary
risks associated with the use of futures contracts are imperfect correlation
between changes in market values of bonds held by the funds and the prices of
futures contracts, and the possibility of an illiquid market.

     Futures contracts are valued based upon their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in the
financial statements. Fluctuations in the value of the contracts are recorded in
the Statement of Net Assets as an asset (liability) and in the Statement of
Operations as unrealized appreciation (depreciation) until the contracts are
closed, when they are recorded as realized futures gains (losses).

     4. DISTRIBUTIONS: Distributions from net investment income are declared
daily and paid on the first business day of the following month. Annual
distributions from realized capital gains, if any, are recorded on the
ex-dividend date.

     5. OTHER: Security transactions are accounted for on the date securities
are bought or sold. Costs used to determine realized gains (losses) on the sale
of investment securities are those of the specific securities sold. Premiums and
original issue discounts are amortized and accreted, respectively, to interest
income over the lives of the respective securities.

B.   The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the funds under methods approved by the Board of
Trustees. Each fund has committed to provide up to 0.40% of its net assets in
capital contributions to Vanguard. At November 30, 1998, the funds had
contributed capital to Vanguard (included in Other Assets) of:

Fund and the Insured Long-Term Tax-Exempt Fund had realized losses totaling
$1,950,000 and $7,986,000, respectively, through November 30, 1998, which are
deferred for tax purposes and reduce the amount of unrealized appreciation on
investment securities for tax purposes (see Note F.) For federal income tax
purposes at November 30, 1998, the funds had the following capital gains
available for distribution, or capital losses available to offset future capital
gains:

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Trustees of Vanguard California Tax-Exempt Funds

[PHOTO]

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
California Tax-Exempt Money Market Fund, California Insured Intermediate-Term
Tax-Exempt Fund, and California Insured Long-Term Tax-Exempt Fund (constituting
Vanguard California Tax-Exempt Funds, hereafter referred to as the "Funds") at
November 30, 1998, the results of each of their operations for the year then
ended, the changes in each of their net assets for each of the two years in the
period then ended and the financial highlights for each of the periods
indicated, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Funds' management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
November 30, 1998 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.

                              The Vanguard Group is
                             named for HMS Vanguard,
                        Admiral Horatio Nelson's flagship
                          at the Battle of the Nile on
                          August 1, 1798. Our founder,
                          John C. Bogle, chose the name
                        after reading Nelson's inspiring
                      tribute to his fleet: "Nothing could
                          withstand the squadron . . .
                       with the judgment of the captains,
                      together with their valour, and that
                        of the officers and men of every
                  description, it was absolutely irresistible."

                        celebrated his 100th birthday on

                                Wellington Fund,
                        The Vanguard Group's oldest fund,
                         was incorporated by Mr. Morgan
                       70 years ago, on December 28, 1928.
                            The fund was named after
                             the Duke of Wellington,
                              whose forces defeated
                            Napoleon Bonaparte at the
                           Battle of Waterloo in 1815.
